044 or Franken Saw?

[wiersy111]

I kinda figured that is what it was but now I have to figure out how to measure it.

With a piece of solder.
Take out the plug and stick the solder in. Rotate the piston to TDC a couple of times. Remove the solder and measure it.

Oh please do tell me

Get some thin solder and bend a small u in it , place a little dab of grease on both sides of risk pin and intake and exhaust.place solder u in grease as close to piston edge as possible. Bolt jug down turn flywheel by hand till you can hardly feel them anymore. Pull jug and mike the flat ends

Thin electrical solder like from the automotive dept at Walmart. Comes in a spiral tube. Run the flywheel back and forth many times over it, until you barely feel it. Like 10 or 12 times. Then measure it.
.020" is a good #

I told you one of the smart guys will show[emoji106] nite fellows

Yea, the thin electrical solder, and just pull the plug and insert the solder till it hits the wall (make damn sure you do not have it inserted in a port, or you will cut it off and have to get it out, so move the piston up, but not all the way up) pull the recoil so it compresses the solder, then measure it with calipers or a micrometer.

As stated, ideal squish is about 20/1000. Usually on a 044/440 it will measure about 37/1000 stock, and deleting the gasket will remove about 17/1000, PERFECT!

I cheat and just measure it straight forward, but it is more accurate if you can measure both left & right over the wrist pin. Unless your piston is worn, it should all be about the same.

You don't want to run less than 17 or 18/1000, cause when the piston gets hot it will contact the top of the cylinder and bad things will happen!

 

[wiersy111]

Well seems pretty straight forward. I will give it a try and see what I come up with.

 

[wiersy111]

Dual Port muffler ordered from HLSupply!

Remove the cylinder and the base gasket between the cylinder and the case. Put the cylinder back on using a good quality sealant for 2 strokes.

Any recommendations on brand of sealant?

Randy likes the Anaerobic Gasket Maker (like Permatex 518**). Any excess will wash away. However, your parts need to be perfectly clean. Lightly sand the surfaces, then clean repeatedly (you will know when it is clean) with brake cleaner. When your rag does not turn grey, it is clean!

 

[huskihl]

I use a thin layer of Motoseal. Dirko, Hondabond, yamabond, 1184 are some others

Anaerobic Gasket Maker (like Permatex 518**) ordered! We are going to get this 044 humming!. The carb tune is going to be interesting. Might have to see if anyone is close to me when I get this done.

Using that sealant everything must be completely oil free and clean clean clean

I love my 044. Delete the base gasket, get a duel port cover, and shave the flywheel key .020 to advance the timing and that saw will make you smile.

+10

Also can try another easy and cheap mod.

I took .010 out of the band and cut base to yield a squish of 20 with the factory metal gasket. Many guys here will do that for $50 for you. Well worth it IMHO.

Add a @Red97 deflector to the starter side of the muffler can and/or a DP cover.

Advance timing like Troller said.

You'll get a saw that runs right on the tail of a well ported one. I wish I still had the one I did this on to compare to one I've fully ported. About 175 psi and wants to 4 stroke well into the 15's.

I agree. This is my first 044 and I built it from a box of parts. It's a 440 bottom end with 10 mm 044 top end. I was shocked how strong it is.

Believe you me, do the jug mod as well. I'm sure Randy can take the job and in state shipping will be cheap for you.

 

[Deets066]

If your goin to pull the jug off, you should be familiar with how it is put together as well. Compressing the rings and installing the jug can be tricky if you have never done it before. A ring compressor kit may be helpful, I think bailey's sells them if I remember right.

I didn't really believe the hype about 044's till I got one.
A nice 10mm which I lightly ported along with DP muffler, gasket delete, .010 from the squish band and sanded the base to set squish at .020.
Got 175 psi and it absolutely smashes through anything in its way tuned to 15000 rpm

3 saws
Stock 72cc 038 mag
Ported 038 mag
Ported 044

I'll probably do that one day.
